PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition extremely reducing creaking sound generated when members grind with each other, maintaining creaking sound reduction effect even when disposed under high temperature for a long time period, and excellent in impact resistance and mold appearance.SOLUTION: There is provided a thermoplastic resin composition for reducing creaking sound, which is a thermoplastic resin composition [X] containing a rubber reinforced vinyl resin [A] obtained by polymerizing a vinyl monomer [b1] in a presence of an ethylene α-olefin rubbery polymer [a1], where the [a1] content is 5 to 30 mass% based on 100 mass% of the thermoplastic resin composition [X], crystallinity index of the [a1] is 1 to 20%, tensile strength of the [a] (T) is 0.5 to 7 MPa, elongation at cutting (E) is 500% or more, hardness (type A durometer) is 40 to 85, Mooney viscosity (ML,°C) is 5 to 60 and a free rubber content in the [X] is 1 to 30 mass%.SELECTED DRAWING: Figure 1 |
